PNEUMATIC TIRE.

To all whom it may concern:

Be it known that we, JOHN GEORGE AULsE- BROOK KITCHEN and IsAAo HENRYSTOREY, subjects of the King of Great Britain and Ireland, residing,respectively, at Lancaster, in the county of Lancaster, and Ambleside,in the county of Westmoreland, England, have invented certain new anduseful Improvements in Pneumatic Tires, of which the following is aspecification.

This invention relates to improvements in the kind of tire described inthe specification of Letters Patent of the United States, No. 948,701,of February 8, A. D. 1910.

The object of the invention is to make a sectional tire similar to thattherein described but without the short internally fitting segmentswhich cover the joint between two principal segments, the usual air tubeor chamber of the tire being modified to act as a substitute for thesaid internal segments.

In the drawing attached hereunto, Figure 1, represents an elevation ofthe improved tire and rim partly in section; Fig. 2 an en larged partiallongitudinal section and Fig. 3 a cross section at w, a", Fig. 2. Fig. iis an enlarged partial longitudinal section through a tire showing themodified form of reinforcement.

In Fig. 1, the tire segments are represented by 1, the rim by 2 and theair chamber or tube by 3. Each segment is secured to the rim in theusual way by means of beaded edges 4 and preferably additionally securedby bolts 5 as usual.

Specification of Letters Patent.

Serial No. 590,009.

Between the segments 1 the ends of which are preferably cut so as tomeet at the rim, a space is left on the tread part and sides, and thetube 3 is provided with transverse ridges 6 adapted to fit between theends of the segments and slightly project above the surface thereof.Where the segments join the ridges 6, the tube 3 is strengthened also,by fabric or canvas insertions such as 7, or alternatively the tube maybe lined for a similar length, as shown at 7 of Fig. 4, the insertionsor linings being also in sections so that the longitudinal elasticity ofthe tube is not much interfered with. The segments 1 are in the drawingshown with molded ridges 8. The molded ridges 6 of the air tubepreferably come to a knife edge above the rim as at 9, Figs. 1 and 2.

What we claim as our invention and desire to secure by Letters Patentis:

In a pneumatic tire the combination of an outer jacket consisting oflongitudinal segments spaced apart at the tread part and of an air tubeformed with transverse ridges adapted to fill in the spaces between thesaid segments.

In testimony whereof we have hereunto affixed our signatures in thepresence of two witnesses.

Signed at Lancaster this 20th day of O0- tober 1910.
